Delve deeper and deeper…the answer is in the puzzle.
The word delve is a verb that means to carry out a search thoroughly or carefully. Delve literally means to dig into the earth.
Eg: The soil specialist delved into the soil to study its characteristics.
The word is used figuratively to mean dig or labour with or as if with a spade.
Eg: He delved into the past, trying to recall the incident.
“We do not plan to delve into her reason for leaving,” said the manager to the staff.
My mother delved into her handbag, hoping to find the bill which was needed as proof.
A word similar to delve is rummage, which means to search, but unsystematically and untidily.
Eg : The thief rummaged through all the drawers trying to find something he could get away with.
So, Rummage! Delve! …The search may be worth the effort!
